Starcloud, a U.S. aerospace startup founded in 2024, plans to deploy Bitcoin mining hardware aboard its Starcloud-2 spacecraft launching later in 2026, betting that solar power and space’s natural cooling can overcome the energy costs crushing profitability for terrestrial miners.
The company’s first satellite, Starcloud-1, successfully operated an NVIDIA H100 GPU in orbit in November 2025.
Starcloud, an orbital data center startup founded in 2024, revealed plans to install Bitcoin mining hardware on its upcoming spacecraft Starcloud-2, expected to launch later this year.
The company has already demonstrated its ability to run high-performance computing hardware in orbit. In November 2025.
It launched Starcloud-1, a satellite carrying an NVIDIA H100 GPU, one of the most powerful AI chips ever operated in space.
By placing computing infrastructure above Earth, Starcloud hopes to take advantage of two key benefits: constant solar energy and natural cooling in the vacuum of space.
Both are critical considerations for cryptocurrency mining, which relies on energy-intensive computational processes to validate transactions on the Bitcoin network.
“We’ll have some Bitcoin mining ASICs on the second spacecraft launching later this year.”
Philip Johnston, CEO of Starcloud, during an interview with HyperChange.
Application-specific integrated circuits (ASICs) are specialized chips designed specifically for Bitcoin mining. They are far more energy efficient than general-purpose GPUs for the task.
The company’s ambition goes beyond a single satellite. Starcloud has proposed deploying as many as 88,000 satellites as part of a massive orbital data center network capable of handling compute-heavy tasks such as AI training and cryptocurrency mining.
Energy costs have long been the dominant factor shaping the economics of Bitcoin mining. The process requires large computing facilities that consume enormous amounts of electricity.
According to Starcloud’s estimates, global Bitcoin mining currently consumes roughly 20 gigawatts of power continuously, comparable to the electricity demand of a small country.
The industry has increasingly faced scrutiny from regulators and environmental groups over energy consumption and emissions tied to large mining farms.
“Bitcoin mining consumes about 20 GW of power continuously. It makes no sense to do this on Earth, and in the end state, all of this will be done in space.”
Philip Johnston, CEO of Starcloud, in a statement posted on X.
In orbit, satellites can generate electricity using solar panels with near-constant exposure to sunlight, while the cold vacuum of space offers passive cooling for heat generated by computing equipment.
The company argues that these advantages could make orbital data centers more efficient than traditional facilities on Earth, where operators often spend significant resources on electricity and cooling systems.
Starcloud’s initiative is part of a growing interest in moving computing infrastructure into orbit. As demand for artificial intelligence and blockchain processing grows, researchers and companies are exploring new ways to meet the massive energy requirements of modern data centers.
Space-based data centers could provide uninterrupted solar power and reduce reliance on terrestrial electricity grids.
The concept has attracted attention from governments, research institutions and private companies investigating how to deploy computing hardware beyond Earth.
The startup says its orbital data center architecture relies on three core technologies: solar power generation, passive cooling through radiative heat loss, and high-speed laser or radio communication to transmit results back to Earth.
If viable at scale, these systems could support not only cryptocurrency mining but also artificial intelligence workloads, scientific research and global communications.
However, the approach remains largely experimental. Launch costs, radiation exposure, and satellite maintenance could still present significant engineering and economic challenges.
The idea of space-based mining highlights how rapidly the infrastructure behind digital assets is evolving.
Profit margins for Bitcoin miners have fluctuated in recent months due to market volatility and changes in mining difficulty.
Bitcoin’s mining difficulty dropped about 7% from its peak of 155.9 trillion to around 145 trillion, offering temporary relief to miners after a period of declining profitability.
New technologies that lower operational costs could therefore reshape the competitive landscape of the industry.
Industry analysts have noted in discussions around orbital data centers, highlighting issues such as satellite reliability and launch costs.
Starcloud’s plan represents a bold experiment rather than an established industry model.
Yet the concept underscores the increasingly global and potentially extraterrestrial scope of cryptocurrency infrastructure.
If Starcloud’s satellite successfully mines Bitcoin in orbit, it would mark the first step toward turning outer space into a new frontier for blockchain computing.
